DISSOLVING APPARATUS.

Original application filed August 23, 1922, Serial No. 583,719. Divided and 1924. Serial No. 728,509.

'To all w om it may concern:

Be it known that we, HARRY D. LATHROP and WALTER H. PAULSON, citizens of the United States, and residents of the city of Chicago, county of Cook, and State of Illinois,have invented certain new and useful Improvements in a Dissolving Apparatus, of which the following is a specification.

Our invention relates to a dissolving apparatus and more particularly to an attachment for a washing machine used for washing bottles and the like, and has for an object the provision of an improved mixing tank or chamber for dissolving washing soda and similar washing substances fully and completely and for delivering a constant flow of washing solution of a uniform strength.

Other objects will appear hereinafter.

This is a division of applicants prior application for washing machine attachments, filed August 23, 1922, Serial N 0. 583,719 now Patent l\ 0. 1,525,304. V

The invention consists in the combinations and arrangements ofparts hereinafter described and claimed.

The invention will be best understood by' reference to the accompanying drawings forming apart of this specification, and in which,

gig. 1 is a top plan view of the invention; an

'Fig. 2 is a vertical sectional view taken substantially on line 22 of Fig. 1.

The preferred form of our invention illus trated in the drawings comprises a mixing receptacle or tank 5 provided with a plug 6 in its bottom for the purpose of draining the tank. A water supply pipe 7 extends vertically along the side of said tank and is provided with a control valve 8. A horizontal pipe 9 extends from pipe 7 substantially half way across said tank andds connected with a discharge pipe 10 leading downwardly into said tank and carrying an inverted dish shaped splash'er 11 at its lower end, arranged preferably a short distance above the bottom of tank 5. A discharge pipe 13 leads from a point adjacent the top of the wall 14 of tank 5 and communicates with an ejector (not shown) of suitable construction or with the wash tank (not shown) into which it is desired to lead or discharge the solution of washing fluid.

' to the this application filed July 26,

In the present instanceI prefer to fill the tank with soda to a level indicated by dotted line 15, the level of the soda in the solution being determined by the operator of the machine and this level of soda varies according particular strength of the solution desired.

In use, the valve is opened permitting water (clear water being preferred) to flow through pipes 7, 9 and 10 and be ejected through splasher memberll. As the water is ejected through said splasher, the force of the water, which is varied by means of the control valve 8, stirs up. the soda at the bottom of the tank 5 and gradually filters or seeps to the top'of the soda where the solution is led off by the discharge pipe 13 to its destination.

In making asoda solution with my improved tank, the soda will last longer and maintain a strong, even solution. .In the old method in making the soda solution, the soda heretofore was washing fluid tank and dissolved in the water therein. This method is costly and a large per cent of the pure soda is wasted, as it is carried off with the solution through thedischarge pipe to its destination. With our invention the water is entered and spread adjacent the bottom of the tank and filters or seeps upwardly. thereby .efiectively dissolving the particles of soda, and the proper uniform solution is carried away from the top of the mixing tank through the discharge pipe 13 to its destination. In this way none of the solid soda itself is carried away by the solution.

While We have illustrated and described the preferred form of construction for carrying our invention into effect, this is capable of variation and modification without departing from the spirit of the invention. We, therefore, do not wish to be limited to the precise details OfCOl'lStIllCtlOIl set forth, but desire to avail ourselves of such variations and. modification as come within the scope of the appended claims,

Having described our invention, what we claim as new and desire to secure by Letters Patent is:

1. In combination, a supply conduit provided with a control valve, a flat bottom receptacle having a discharge opening formed in one of its side walls adjacent the top edge poured directly into the same thereof, a conduit mounted in said openingito provide an overflow, a conduit having connection with the supply conduit and extending over the edge of said receptacle and downwardly centrally within the receptacle a short distance from the bottom thereof, and a cup shaped member mounted on said outlet end for distributing fluid in the lower part of said receptacle.

2 A dissolving apparatus including in combination, a mixing tank With an overflow opening adjacent its top and a discharge pi e extending theretronnsaid tank having a at bottom and being adapted to be substantially filled with a soluble substance to a point slightly below said overflow opening, drain means at the bottom of said tank, a supply conduit with a control valve adjacent said itvaoaa tank, a conduit connected with said supply conduit and extendlnphorizontally over the edge of said tank and having. a portion extendingcentrally downwardly into said tank with its outlet end a short distance from the bottom thereof, and a dome shaped member rcinovablymounted on the outlet end of said conduit portion for distributing fluid ad- HARRY D.
